Space Debris Has Hit and Damaged the International Space Station (sciencealert.com) 38

A user shares a report from ScienceAlert: The inevitable has occurred. A piece of space debris too small to be tracked has hit and damaged part of the International Space Station -- namely, the Canadarm2 robotic arm. The instrument is still operational, but the object punctured the thermal blanket and damaged the boom beneath. It's a sobering reminder that the low-Earth orbit's space junk problem is a ticking time bomb. Canadarm2 -- formally known as the Space Station Remote Manipulator System (SSRMS), designed by the Canadian Space Agency -- has been a fixture on the space station for 20 years. It's a multi-jointed titanium robotic arm that can assist with maneuvering objects outside the ISS, including cargo shuttles, and performing station maintenance.

It's unclear exactly when the impact occurred. The damage was first noticed on 12 May, during a routine inspection. NASA and the CSA worked together to take detailed images of and assess the damage. "Despite the impact, results of the ongoing analysis indicate that the arm's performance remains unaffected," the CSA wrote in a blog post. "The damage is limited to a small section of the arm boom and thermal blanket. Canadarm2 is continuing to conduct its planned operations." Robotics operations on the ISS using the Canadarm2 will continue as planned for the near future, the CSA said. But both space agencies will continue to gather data in order to perform an analysis of the event, both to understand how it occurred, and to assess future risk.

    • An unfamiliar name so I looked it up. From Wikipedia "The Kessler syndrome (also called the Kessler effect, collisional cascading, or ablation cascade, proposed by NASA scientist Donald J. Kessler in 1978, is a theoretical scenario in which the density of objects in low Earth orbit (LEO) due to space pollution is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations." Whether or not the Kessler syndrome is near or not the light pollution from thousands of communications satellites will end ground based astronomy before much longer. Most planets seem to have rings around them so the Earth will likely have one sometime in the future from orbital trash we put up there. I wonder if it should be included in exoplanet surveys as a likely signature for space-fairing civilizations.

        And somehow all that debris, after playing the most chaotic game of billiards, is supposed to end up in the exact same orbit??

        Perhaps that's not how rings are formed.

      There is no indication this was man-made debris that I can find. It may have been a micro meteorite.

    They don't know when it happened - they only discovered it during a routine inspection, and there doesn't appear to be any functional change (if there was, they'd likely know when this happened).

    The story seems unnecessarily alarmist, even if you're concerned about (what I think is) a very real problem with space junk. Ever hear about the boy who cried wolf?

      What worries me is that they didn't know about it while still having the arm in use several times.

      This time it was small and negligible. What if it was larger and caused a complete failure of the arm during operation. Like when a bearing got smashed or some hydraulics got damaged maybe? Making the arm go in a wrong direction uncontrollable while operating it. Could easily cause more damage to other parts of the station.

      I would propose they hang much more camera's all over the place and do some automated ima

      the "story" just recounts exactly what you said, which is just factual information. how is this being alarmist or crying wolf?

          that's a pretty much apt metaphor imo. it doesn't predict doom but highlights that the issue is not really fully under control. bad things can happen at any moment until we find a definitive solution for this, yet we keep shooting junk up there.

          maybe it isn't any really serious direct hazard to us down on earth ... except we might have to manage without satellites for a while. but that's not going to be trivial, could potentially be really nasty and, yeah, many would call that metaphorically "a bomb".

      I agree with you. This isn't the first time space debris has damaged the space station, and it won't be the last. They've had damage to their windows and solar panels as well. Doesn't mean the debris issue doesn't need to be fixed, just means that space is dangerous. No surprises there.

      And why exactly would you attempt to label this a Boy-Who-Cried-Wolf problem? Is this the latest story in a barrage of clickbait bullshit being pimped by the MSM for the third time this week? If you think this is a "very real" problem, then what exactly is your problem of the news stations talking about it on the rare occasion that it occurs?

    It's only a matter of time statistically. It may never happen soon and it may happen sooner than expected. Without force fields (shields) like we see in science fiction or more down to earth, an "iron dome"' [wikipedia.org], something bigger will eventually cause the complete loss of a space station like this one.

    It doesn't necessarily have to be space debris, it could be meteorites or anything else traveling through space at tremendous speeds.

    Let's face it, currently the space station doesn't have any other alternatives than modifying its orbit trajectory to avoid collisions and it's a rather kind of slow solution where you have to know and plan in advance.

    • It's gonna have to be point defense because we only have an idea of how to make deflector shields for [certain types of] energy, not for objects.

      However, point defense wouldn't have worked here because the object wasn't being tracked...

    • It's unlikely they would have an issue with bigger objects - Those are detectable, and they move the station out of the way of them routinely. It's the tiny objects like this one that can happen without knowing.

      How many tools does the average consumer have that are functional, mission critical and that are 20 years old? Granted, not a fair comparison, but still. I'd guess better engineering than luck. Surely the ''next gen'' will even improve.

  • Where did this debris come from? Classifying it as debris suggests a man-made source, so probably a blown up satellite. It is things like this that make the need for global treaties banning orbital action weapons critical. Other issues in space require the same treatment - assuming burn-up reliant reverse supply chain is risky in more ways than the simplistic "it goes away" assumption implies. Material is distributed throughout the atmosphere, so it matters what that material is and requires consideration n
    • Classifying it as debris suggests a man-made source...

      A quick dictionary check [merriam-webster.com] does not support a theory that debris must be man-made. For example, tornados and geologic erosion are both common sources of debris.

  • Send out the Space Force and rake that debris!
  • Duct tape!

    Looking forward to the space walk where NASA applies what is an extremely cheap repair to an extremely expensive piece of equipment.

  • Why is it assumed it's space debris? Was it identified as man made?

  • If you look at a radar type image of the debris floating around this planet (the debris that can be tracked) you think to yourself if an "alien" were to try to invade earth, they would see that and say, Ummm no...look at that force field around that planet. LOL
